CVE-2025-6023
Description
A Cross-site scripting (XSS) vulnerability was found in Grafana caused by client path traversal and open redirect. This flaw allows attackers to redirect users to malicious websites that execute arbitrary JavaScript code in scripted dashboards. Unlike many other XSS vulnerabilities, this vulnerability does not require editor permissions. If anonymous access is enabled, the XSS attack will be successful.
Statement
No Red Hat products or offerings are affected by this vulnerability. As the version of grafana (9.2.10/10.2.6) shipped in this version of Red Hat Enterprise Linux is not vulnerable to this CVE. The vulnerable versions listed in the CVE posting are 12.0.x, 11.6.x, 11.5.x, 11.4.x, and 11.3.x, which are all not in Red Hat Enterprise Linux.
This vulnerability is Important because it combines two high-impact vectors—open redirect and stored/reflected XSS—without the common mitigation of requiring elevated permissions. The lack of an editor-role requirement drastically expands the attack surface, enabling exploitation by any unauthenticated attacker if anonymous access is enabled. In Grafana deployments that allow public or wide internal access, an attacker could craft a malicious link that both redirects users to attacker-controlled domains and executes arbitrary JavaScript in scripted dashboards. This can directly lead to session hijacking, credential theft, or full account compromise, potentially allowing an attacker to modify dashboards, extract sensitive data from Grafana data sources, or pivot into connected systems.
Mitigation
Alternatively, you can block this attack by adding the default Content Security Policy configuration as suggested in the Grafana Documentation.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Access Control,Confidentiality
Technical Impact: Bypass Protection Mechanism; Read Application Data
The most common attack performed with cross-site scripting involves the disclosure of private information stored in user cookies, such as session information. Typically, a malicious user will craft a client-side script, which -- when parsed by a web browser -- performs some activity on behalf of the victim to an attacker-controlled system (such as sending all site cookies to a given E-mail address). This could be especially dangerous to the site if the victim has administrator privileges to manage that site. This script will be loaded and run by each user visiting the web site. Since the site requesting to run the script has access to the cookies in question, the malicious script does also.
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
In some circumstances it may be possible to run arbitrary code on a victim's computer when cross-site scripting is combined with other flaws, for example, "drive-by hacking."

The consequence of an XSS attack is the same regardless of whether it is stored or reflected. The difference is in how the payload arrives at the server. XSS can cause a variety of problems for the end user that range in severity from an annoyance to complete account compromise. Some cross-site scripting vulnerabilities can be exploited to manipulate or steal cookies, create requests that can be mistaken for those of a valid user, compromise confidential information, or execute malicious code on the end user systems for a variety of nefarious purposes. Other damaging attacks include the disclosure of end user files, installation of Trojan horse programs, redirecting the user to some other page or site, running "Active X" controls (under Microsoft Internet Explorer) from sites that a user perceives as trustworthy, and modifying presentation of content.
